Cartridge Mechanical Seals – Auxiliary Elements

In order for a mechanical seal to work correctly, it is essential to guarantee adequate lubrication and refrigeration. In some applications, this is achieved thanks to the use of a secondary fluid, when the primary fluid does not possess the necessary properties. The provision of this additional fluid involves the inclusion of a secondary circuit, which may be open or closed, and may or may not be under pressure. In the case of opting for an open circuit, the complexity and installation costs are very low, but fluid consumption (usually mains supply water) can become a problem, above all due…

The Dry Seals sealing system as a solution for the chemical industry

The chemical sector involves working with aggressive powdered substances, these substances erode fundamental parts that ensure the proper functioning of the equipment; these include screw conveyors, rotary valves and internal agitators. The abrasive nature of these substances is coupled with the difficulty of having to maintain a specific and suitable level of humidity for the vast majority of applications. This removes lubricating or coolant fluids of any nature from the equation, and this is where the Dry Seals come to the fore.   Which specific applications do we recommend the Dry Seals sealing system for? As we indicated above, the…

LDC40 AGITATOR CARTRIDGE SEAL

As already seen in the previous blog entry, in an agitator/reactor, it is very likely that a cartridge seal will operate under dry conditions, as the fluid/product is at the bottom of the system and hardly enters into contact with the seal. In such conditions, it is essential to use a lubricant other than the product fluid. The LDC40 cartridge seal is a double seal that facilitates the use of a secondary fluid (barrier fluid) to lubricate the seal. Another benefit of using a secondary fluid is that the maximum linear operating speed of the seal is higher than that…
